WeitereVorteile ergeben sich aus den Unteransprüchen.FurtherAdvantages result from the subclaims.

DieErfindung wird nun anhand von Abbildungen näher erläutert:TheInvention will now be explained in more detail with reference to figures:

Inder1a ist ein erfindungsgemäßer Übertragerkopfdargestellt, wobei in1b einvergrößerter Ausschnittdes linken Endbereichs gezeigt ist. Er ist flach ausgeführt undbenötigtein geringes Bauvolumen.In the 1a A transmitter head according to the invention is shown, wherein in 1b an enlarged section of the left end region is shown. It is flat and requires a small volume.

Dabeisind auf den Träger1 Ferritkerne2 aufgebrachtund verbunden, insbesondere als Klebeverbindung oder als lösbare Verbindung,wie Schraubverbindung oder dergleichen.Here are on the carrier 1 ferrite Cores 2 applied and connected, in particular as an adhesive connection or as a releasable connection, such as a screw connection or the like.

Anden Ferritkernen2 ist eine mehrlagige Platine mit Lagen(3,4,5) vorgesehen, die als flache Wicklungenausgebildete Leiterbahnen aus Kupfer tragen und somit auf der Platineausgeführtsind.On the ferrite cores 2 is a multi-layer board with layers ( 3 . 4 . 5 ) are provided, which carry copper conductor tracks designed as flat windings and are thus designed on the circuit board.

Ineinem anderen erfindungsgemäßen Ausführungsbeispielwird dabei eine einzige ebene spiralförmige Wicklung als Leiterbahneiner einlagigen Platine vorgesehen, wobei dann allerdings weniger elektrischeLeistung übertragbarist.Inanother embodiment of the inventionbecomes a single flat spiral winding as a conductor tracka single-layer board provided, but then less electricalPerformance transferableis.

Inanderen erfindungsgemäßen Ausführungsbeispielen,insbesondere nach1a und1b, wird dabei eine mehrlagigePlatine (3,4,5) eingesetzt, die in mehrerenEbenen eine spiralförmigeWicklung aufweist. Insbesondere verläuft die Leitung des Stromesdabei nicht nur in einer einzigen spiralfömigen jeweiligen Ebene sonderndie Leitung wechselt mehrfach zwischen den Ebenen zur Verminderung desSkin-Effektes. Das heißt,dass vorteiligerweise nach einem kurzen Leiterbahnabschnitt einWechsel in eine nächsteEbene der Platine erfolgt, dort wieder ein kurzer Leiterbahnabschnittdurchlaufen wird und dann wiederum gewechselt wird. Auf diese Weise entstehteine quasi verdrillte Stromführung,die vom Grundprinzip her einer Litze entspricht, also einem mehrfachenBündelgegenseitig isoliert ausgeführter Stromleitungen.Die so entstandene Wicklung ist also quasi-verdrillt ausgeführt.In other exemplary embodiments according to the invention, in particular according to 1a and 1b , a multi-layer board ( 3 . 4 . 5 ) used, which has a spiral winding in several levels. In particular, the conduction of the current does not only run in a single spiral-shaped respective level, but the line alternates several times between the levels in order to reduce the skin effect. This means that after a short conductor track section, a change to a next level of the circuit board advantageously takes place, a short conductor track section is run through again there, and then another switch is made. In this way, a quasi twisted current conduction is created, which corresponds in principle to a stranded wire, that is to say a multiple bundle of mutually insulated power lines. The winding thus created is thus quasi-twisted.

In2 ist der gesamte Aufbaudes Übertragerkopfesmit die Wicklung tragender Platine3 gezeigt. Die Platine3 trägt zusätzlich auchElektronikbauteile23 und weist die notwendigen Leiterbahnen auf.In 2 is the entire structure of the transmitter head with the winding-supporting circuit board 3 shown. The circuit board 3 also carries electronic components 23 and has the necessary conductor tracks.

DiePlatine3 und die Ferritkerne4 sind mit einemGehäuseteil21 verbunden,das auch Kühlrippen22 zurWärmabfuhraufweist.The circuit board 3 and the ferrite cores 4 are with a housing part 21 connected, that also cooling fins 22 for heat dissipation.

In3 ist ein anderes erfindungsgemäßes Ausführungsbeispielgezeigt. Dabei liegen auf dem Ferritkern31 Kunststoffformteile32,in deren Vertiefungen die Litzen33 eingebettet sind. In3a fehlen die Litzen. Inder linken oberen Hälfteder3 und3a ist ein symbolischer Schnittdurch die Kunststoffformteile32 gezeigt mit der Andeutungzweier eingelegten Litzen33. Die Kunststoffformteile32 erleichterndas Einlegen der Litzen33. Der Ferritkern31 istE-förmigausgeführtund die Wicklung ist um den mittleren Schenkel des E herum ausgeführt. Dabeisind die drei Schenkel des E sehr kurz ausgeführt, insbesondere so kurz wiedie Höheder Wicklung ist.In 3 another exemplary embodiment according to the invention is shown. Thereby lie on the ferrite core 31 Plastic moldings 32 , in the recesses the strands 33 are embedded. In 3a the strands are missing. In the top left half of the 3 and 3a is a symbolic cut through the molded plastic parts 32 shown with the suggestion of two inserted strands 33 , The plastic molded parts 32 make it easier to insert the strands 33 , The ferrite core 31 is E-shaped and the winding is carried out around the middle leg of the E. The three legs of the E are made very short, in particular as short as the height of the winding.

Inder4 ist der Teil zurinduktiven Energieübertragungdes Systems gezeigt. Dabei sind im Boden41 zwei aus LitzeausgeführtenLinienleiter42 eingelegt, die einen gegenseitigen AbstandA von 140 mm aufweisen. Bei anderen erfindungsgemäßen Ausführungsbeispielensind auch Werte von 100 mm bis 200 mm vorteilig.In the 4 the part for inductive energy transmission of the system is shown. Doing so are in the ground 41 two line conductors made of stranded wire 42 inserted, which have a mutual distance A of 140 mm. In other exemplary embodiments according to the invention, values from 100 mm to 200 mm are also advantageous.

Derflache, in einem Gehäuseteil43 vorgesehene Übertragerkopfweist einen maximalen Abstand B zum Boden41 von 15 mmauf, also etwa ein Zehntel des Abstandes A der Linienleiter. Statteines Zehntels sind Werte zwischen 7 % bis 12 % vorteilhaft.The flat one in one housing part 43 provided transmitter head has a maximum distance B to the ground 41 from 15 mm to about a tenth of the distance A between the line conductors. Instead of a tenth, values between 7% and 12% are advantageous.

Diesegenannten geometrischen Merkmale werden bei der Erfindung erreicht,indem die Wicklung flach ausgeführtist. Die Leitungen der Wicklung liegen dabei in einer Ebene und überkreuzensich nicht.Thismentioned geometric features are achieved in the invention,by making the winding flatis. The lines of the winding lie on one level and cross overnot yourself.

Inanderen erfindungsgemäßen Ausführungsbeispielensind die Kunststoffformteile32 als aneinander anreihbareModule ausgeführt,deren Vertiefungen derart gestaltet sind, dass die Litze entwederin gerade Linien einlegbar ist oder in Kreisbogenstücke. Dazusind sowohl die geraden als auch die kreisbogenfömigen Verläufe als Vertiefung in das ursprünglicheKunststoffteil derart eingeprägt,dass Erhöhungenzurückbleiben,die zueinander teilweise unterbrochen sind, also nicht alle direktaneinander anschließen.In other exemplary embodiments according to the invention, the plastic molded parts are 32 as modules can be arranged next to one another, the recesses of which are designed in such a way that the strand can either be inserted in straight lines or in circular arc pieces. For this purpose, both the straight and the circular-shaped courses are embossed as a depression in the original plastic part in such a way that ridges remain which are partially interrupted with respect to one another, that is to say not all of them connect directly to one another.

Der Übertragerkopfist in einem gegenüber demBoden relativ bewegbaren Fahrzeug oder Maschinenteil eingebaut,das in den Figuren nicht gezeigt ist.The transmitter headis in one against thatGround relatively movable vehicle or machine part installed,that is not shown in the figures.

Vorteiligerweisearbeitet das erfindungsgemäße Systemzur berührungslosenEnergieübertragungnach den in derDE44 46 779 C2,DE100 53 373 A1 und/oderDE 197 35 624 C1 angegebenen elektronischenund elektrischen Merkmalen und ist entsprechend ausgeführt. ImUnterschied zu diesen Schriften ist jedoch die Leistungsübertragung,insbesondere der Übertragerkopf,mit besonders geringem Bauvolumen ausgeführt.Advantageously, the system according to the invention for contactless energy transmission works in accordance with the DE 44 46 779 C2 .
